The full form of TFT is "Thin Film Transistor". It is a display technique used in LCD (Liquid Crystal Display). The active component that acts as a switch for each pixel to be turned on and off is the TFT. These are made up of a wide variety of semiconductor compounds similar to silicon.
Important points about TFT
In a TFT, one to four transistors regulate each pixel. Among all flat panel processes, TFT technology is known for its high resolution, but it is also quite expensive.
TFT screens are often referred to as active matrix LCDs because each pixel uses a transistor organized in matrix form.
Advantages of TFT
- The key advantage of TFT technology is that each pixel on the display has a separate and small transistor.
- Since the image is updated many times per second, this allows the display to refresh fairly quickly.
